SPINDLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 554,514, dated February11, 1896.

Application filed August 15,1895- Serial No. 559,359. (No model.)Patented in England July 25,1894=,N0-14,261.

T0 aZZ whom it may concern:

Be itknown that I, EDWIN HITCHON, a subject of the Queen of GreatBritain, and a resident of Accrington,in the county of Lancaster,England, have invented a certain new and useful Improvement inSpindle-Supports, (for which I have obtained British Letters Patentnumbered 14,261, dated July 25, 1894,) of which the following is aspecification.

My present invention is an improvement upon the spindle-support which isthe subject of my United States Patent No. 530,073. In that patent Ihave shown, described, and claimed a combination of instrumentalitiesamong which is a cross-bearing on the bolster base or flange andtangential to the bolster for receiving a rock-shaft having at one endan arm which carries a cover for the oil-tube and at or near the otherend an arm which carries a spindle-holder, the rock-shaft being held inposition to cause the device carried by it to cover the oil-tube and tohold the spindle by a counterweight or its equivalent, such as a spring.In the embodiment of my invention shown in said patent the crossbearingis a continuous unbroken tube, the combined holder-cover and rock-shaftis of wire, and this wire must be partly bent into its ultimate shapeafter the shaft portion of the wire has been inserted into shape.

By my present improvement I am enabled to make the device (except ofcourse the cross-bearing) in a single casting and to bring it intofinished shape before placing it in position on the spindle-bolster.

The nature of the improvement can best be explained and understood byreference to the accompanying drawings which will first be described,after which the improvement will be more particularly pointed out in theclaim.

In the drawings, Figure 1 is an elevation from the side of thespindle-bolster on which the oil-tube is located, with the rock-shaftand its attached parts removed. Fig. 2 is a like View with therock-shaft and its detached parts in place. Fig. 3 is an elevation fromthe side on which the cross-bearing is located. Fig. 4 is a plan. Fig. 5is a view of the rockshaft and its attached parts.

A is the spindle; B, the bolster; G, the upright oil tube; 0, thehorizontal branch thereof which puts the oil-tube in communication withthe bolster; D, the cross-bearing for the rock-shaft formed on thebolster base or flange and tangential to the bolster; a, the rock-shaft;b, the oil-tube cover; 0, the upright carrier-arm for said cover; 6, thespindle-holder; d, the upright carrier-arm for said holder, and f thecounterweight. These parts in their general combination and arrangementresemble the corresponding parts in my patented device hereinbeforereferred to and are distinguished by the same reference letters.

In the tubular cross-bearing D is formed a longitudinal slot or openingg, which extends from end to end of the bearing. This permits therock-shaft with its attached parts to be readily placed in position byinserting the shaft endwise into the bearing with the coverarm 0foremost and traveling along through the slot 9 until that arm passesout from the slot beyond the far end of the bearing D. Then if therock-shaft be released, its counterweight will turn it in a direction tocause the cover I) to close the oil-tube and the holder 6 to overhangthe spindle-wharve, by which movement the arm a will be carried out ofregister with the slot g. The same movement carries the holder-arm clalso out of register with the slot, although in fact that is hardlynecessary, inasmuch as this arm, as shown, is thicker than the width ofthe slot, so that it could not in any event pass therethrough. Thecover-arm c is on the contrary made thin at its base so that it willpass easily through the slot. The distance between the two arms a disabout equal to the length of cross-bearing D, so that after therock-shaft has been inserted in the bearing a distance sufficient tobring the cover-arm 0 just beyond the far end of that hearing and thenhas rocked to throw its arms (I 0 forward or toward the spin dle andoil-tube said shaft will be locked firmly against endwise movement byits arms 0 d, which lie at and against opposite ends of thecross-bearing. The slot 9 is formed along such a line relatively to thearms d and c that they can be rocked back far enough to uncover theoil-tube and release the spindle without bringing the arm a intoregister with the slot. In other words, to bring the arm 0 into registerwith the slot g it must be rocked backward to an extent considerably-inexcess of the movement by which the oil-tube is uncovered. Thus underall normal conditions the rock-shaft will be restrained from lengthwisemovement and the cover and holder consequently will be maintained inproper position, while at the same time the shaft and its attached partscan instantly be removed whenever occasion requires it. I am alsoenabled to make the rock-shaft and its attached device, whether acasting or not, into finished shape before fitting the same to thecrossbearing.

As provided in my aforesaid patent, I may use a spring instead of acounterweight, and I desire to be understood as including any suchsubstitution in my claim.

What I claim, and desire to secure by Letters Patent, as an improvementupon the spindle-support which is the subject of my Letters Patent No.530,073, dated November 27, 189i, is-

The combination with the spindle, bolster and oil-tube of thecross-bearing on the bolster base or flange tangential to the bolsterprovided with the longitudinal slot g extending from end to end of thebearing, and the cross-shaft, the oil-tube cover and spindle holder andthe two carrier-arms for said cover and holder, said arms when inoperative position being at opposite ends of the cross-bearin g and outof register with the slot thereinand the slot being so located withreference to the arms, that the cross-shaft carrying the latter can berocked back far enough to uncover the oil-tube and release the spindlewithout bringing said arms into register with the slot as hereinbeforeshown and described.

In testimony whereof I have hereunto set my hand this 1st day of August,1895.
